Japan likely to revise budget due to wage data flaws - finmin

TOKYO, Jan 11 (Reuters) - Japan's government is likely to revise its budget draft for the next fiscal year to pay for a shortfall of employment insurance benefits caused by flaws in the country's wage data, Finance Minister Taro Aso said on Friday.

The likely budget revision - a rare move - follows the revelation that the labour ministry has underestimated workers' average wages for years. The data is used to set levels of unemployment benefits paid partly by state coffers. (Reporting by Tetsushi Kajimoto; Editing by Chris Gallagher)
